Multi-Core Sheathed Wire to Insulated Spade Terminal Wire Harness

Customized wire harness using multi-core sheathed wire as the main conductor, terminated with insulated spade terminals, designed specifically for applications requiring simultaneous transmission of multiple power or signal lines with terminals that offer good insulation protection. It is widely used in household appliances, machinery equipment, automotive electronics, industrial control cabinets, and various electrical/electronic devices requiring quick plug-in connection with switches, relays, terminal posts, and other components. Multi-core sheathed wire refers to a composite wire structure in which multiple individually insulated conductors are bundled together and enclosed within a single outer sheath. 
Compared with individual loose wires, multi-core sheathed wire offers stronger overall integrity, easier wire routing and securing, a neater appearance, and effective protection against insulation damage caused by mutual friction or tangling among individual wires during use — making it particularly well-suited for equipment requiring simultaneous transmission of multiple power or signal lines with certain requirements for overall wire aesthetics and durability.
The outer sheath material is made of premium wear-resistant, aging-resistant, and flame-retardant material (such as PVC or TPE), effectively resisting damage to the internal conductors caused by external environmental factors such as friction, pulling, oil contamination, or moisture during long-term use, fully ensuring the electrical safety and service life of the entire harness. 
The spade terminal at the end of the harness features an insulated sheath design, meaning that the base of the metal spade terminal and the exposed metal contact area are covered with a layer of premium insulating material. Once mated, this effectively encloses the metal portion of the terminal, preventing accidental contact between operators or other internal conductive components and exposed metal — thereby eliminating potential short-circuit or electric shock hazards. The insulating sheath itself also provides a degree of fixation and protection for the terminal, effectively preventing loosening or detachment caused by vibration or impact during long-term use or transport.
The spade terminal body is precision-stamped from high-quality copper alloy and surface-treated with tin plating, offering excellent conductivity and oxidation resistance, with smooth insertion/removal and stable, reliable contact that mates well with the vast majority of corresponding socket-style components on the market (such as switches, relays, fuse holders, and motor terminal posts). Common spade sizes include 2.8mm, 4.8mm, 6.3mm, and other dimensions, flexibly selectable according to the interface specifications of the customer's actual mating components. We support in-depth customization of the number of cores in the sheathed wire (such as 2-core, 3-core, 4-core, or more), conductor wire gauge, overall harness length, sheath color, and the specific spade terminal specification and insulating sheath color according to each customer's actual device interface standards, truly achieving on-demand, flexible production. During production, we strictly implement continuity testing, tensile strength testing, insulation resistance testing, and terminal crimp strength testing as part of a multi-layered quality control process, ensuring every harness meets relevant industry standards before shipment. This enables us to provide customers with a safe, reliable, and neatly organized customized wire harness solution, serving industries such as household appliances, automotive electronics, industrial automation, and machinery manufacturing.
